The screen has to be there for a reason or else why would my granatelli MAF have one.

 

i kinda got a free mod that i did but its like 20 bucks and very easy to do. first you take the top of your air box off and take the old filter out. while you have the filter out you might as well rip that maf screen out too. go down to your local parts store and pick up a cone filter and make sure it has a 4 inch inlet. this will slip right over you maf sensor. i made a bracket that goes from the stock air bock screw hole to the maf sensor to hold the filter steady and really worked out great, definately noticed a difference.

and yes i know my engine bay was extremely dirty in the pic but this is when i first did this mod and the bracket i made is not shown in the pic either. if you want i will get updated pics as i now have the air raid modular intake tube.

 

dude the screen is just there for emissions from the factory. theres all kinds of bs on factory vehicles and once you elimate all that crap youll notice a huge difference. if you think its gunna mess somethin up, dont do it, but half the people on this site have it done and it doesnt mess there trucks up and im one of them.

I didn't wana do it so that's why I got an aftermarket one

 

Mine has been gone for several months, and no issue noticed. But some power increase. I do wonder if the range that theaftermarket sensor can read is higher than the stock unit though.

 

oh im sure. its a smoother surface and bigger diameter and eliminating that screen just helps it breathe even more.

 

I just don't see the need for a bigger MAF as the hp increase isn't worth the price (to me)

 

agreed.

When I said 'purify' I meant the flow, not the air itself. I've removed my MAF and haven't seen any problems. I'm sure it probably does help streamline the air, but with the width of the screen being less than an inch, it probably doesn't streamline it too much. You need a decent travel to get the molecules to head 'down' the tunnel and the screen just doesn't have that.

I've seen no pinging or anything else. If anything, I've seen a slight increase in power off the line. (now I need to get some real sway dampening because stomping on it in a turn causes the whole truck to rock

 

I didn't mean a bigger MAF, just one that reads a wider range.
